Make sure mClearAll is true after calling GetNaturalSize()
Currently, GetNaturalSize() sets mClearAll to false.
It can make bug when calling GetHeightForWidth right after
GetNaturalSize().

Added automatic premultiplication of image visual images
To prevent scaling quality issues, image visual images are pre-multiplied after loading.
By default, this is on, but it can be turned off via a new API in VisualFactory.

Change if statement for text scrolling.

Check line is empty or not before getting line of character
mLine can be empty Vector if there is no text or place holder in
text-editor / text-field.
So check mLine is empty or not first and if it is empty, return 0u.
